Processes do not need to address their communication partner, i.e., are completely decoupled in reference. 2. Communication is asynchronous since the space guarantees persistent storage of data, i.e., processes are completely decoupled in time. 3. The processes run in completely different computational environments as long as they can access the same space, i.e., processes are completely decoupled in space. 6 Semantic Web Technology • Shortcomings of the current Tuple Space models: • • • • lack of namespaces lack of unique identifiers lack of semantics (how do tuples relate in the space) structures (ontologies) for describing the information content of the tuples • RDF/RDFS, WSMO! • Graphs of <subject predicate object>-triples make up a structured Triple Space! 7 Web Service Technology • • • Current Web Services technologies (WSDL, SOAP, UDDI) are not so much about the Web They mainly use (synchronous) message exchange over Web protocols Process and application integration is inflexible • How did the Web revolutionize human communication? By persistent publication, and searching information put by others on the Web This is much closer to TupleSpaces than to RPC-Style Web Service Technologies around WSDL and SOAP! 8 A Convergence of Technologies Semantic Web + Web Services Semantic Web Services Semantic Web + Tuple Spaces Triple Space Semantic Web Services + Triple Space 9 Triple Spaces Triple Spaces provide a communication paradigm for anonymous, asynchronous information exchange that ensures the persistency and unique identification of the communicated semantic, semi-structured data. 10 Message Message Base Services Peer Application Services Applications Internet Process Editor Mapping Editor Ontology Editor Goal Editor Management Discovery Process Mediation Negotiation and Contracting Orchestration Planning Data Mediation Communication Choreography Reasoner Semantic Repository Triple Space Vertical Services Message Vertical Services Management & Monitoring Developer Internet End User Triple Space Communication Message Peer 11 Triple Space Communication Basic entities: • Triples The semantic data exchanged or shared • Triple Space The space used to exchange or share triples • Triple Space server The infrastructure / server hosting Triple Spaces 12 Triple Space Communication Triple Space architecture: • Communication protocol for data exchange • Communication interfaces • e.g., write(triples) and read(query) over HTTP • Triple Space operations layer • • • • Query handling Reasoner bindings Triple Space management (delete, empty, create…) Data Store management (resource bindings…) • Storage component • RDF Store, file system… 13 Core Objectives from the Proposal 1. Improve the ideas of Tuple Space computing by adding semantics 2. Integration of Web service infrastructure with the newly emerging Triple Space 3. Establishing a novel Semantic Web service paradigm 4. Address the lack of standardized business data ontologies 5. Scalable and linkable Triple Space storage 6. Security and trust mechanisms 14 History Semantic Web + Web Services Semantic Web Services A Conceptual Model for SWS A Formal Language for WSMO Execution Environment for WSMO 15 History (2) Semantic Web + Tuple Space Triple Space Triple Space Computing (TSC) funded by FFG Austria D.

Enhance existing products of the commercial partners of TripCom, e.g. Telefonica 1. Leverage TripCom implementations of semantically enhanced service interaction patterns 2. Target BPEL Standardization 3. Incubator programme for "Serviceoutsource.com" 4. Target public sector as early adopter 2. Identify new business possibilities / raise venture capital for new start-ups, e.g. CEFRIEL 3. Address other companies via our dissemination strategy 21
